VisiGene is a virtual microscope for viewing in situ images.
These images show where a gene is used in an organism, sometimes down to
cellular resolution. With VisiGene users can retrieve images that meet specific search criteria, then interactively zoom and scroll across the collection.

Good search terms include gene symbols, authors, years, body parts,
organisms, GenBank and UniProt accessions, Known Gene descriptive terms,
Theiler stages for mice, and
Nieuwkoop/Faber stages for frogs. The wildcard characters
* and ? work with gene symbols; otherwise the full word must match.

Image Navigation

Following a successful search, VisiGene displays a list of thumbnails of
images matching the search criteria
in the lefthand pane of the browser. By default, the image corresponding to
the first thumbnail in the list is displayed in the main image pane.
If more than 25 images meet the search criteria, links at the bottom of
the thumbnail pane allow the user to toggle among pages of search results.
To display a different image in the main browser pane,
click the thumbnail of the image you wish to view.

By default, an image is displayed at a resolution that provides
optimal viewing of the overall image. This size varies among images.
The image may be zoomed in or out, sized to match the resolution of the
original image or best fit the image display window, and moved or
scrolled in any direction to focus on areas of interest.

Zooming in: To enlarge the image by 2X, click the Zoom in
button above the image or click on the image using the left mouse button.
Alternatively, the + key may be used to zoom in when the main image pane is
the active window.

Zooming out: To reduce the image by 2X, click the Zoom out
button above the image or click on the image using the right mouse button.
Alternatively, the - key may be used to zoom out when the main image pane
is the active window.

Sizing to full resolution: Click the Zoom full button above
the image to resize the image such that each pixel on the screen
corresponds to a pixel in the digitized image.

Sizing to best fit: Click the Zoom fit button above
the image to zoom the image to the size that best fits the main image
pane.

Moving the image: To move the image viewing area in any direction,
click and drag the image using the mouse. Alternatively, the following
keyboard shortcuts may be used after clicking on the image:

Scroll left in the image: Left-arrow key or Home key

Scroll right in the image: Right-arrow key or End key

Scroll up in the image: Up-arrow key or PgUp key

Scroll down in the image: Down-arrow key or PgDn key

Downloading the original full-sized image: Most images may be viewed
in their original full-sized format by clicking the "download"
link at the bottom of the image caption. NOTE: due to the large size of
some images, this action may take a long time and could potentially exceed
the capabilities of some Internet browsers.
